An OWL ontology server for OWL API programs, e.g., Protégé Desktop.
The server plugin (v3) for Protégé 5 is under construction. The previous version of the server (v2) works for Protégé 4, and is documented in the links below:
User docs: http://protegewiki.stanford.edu/wiki/Protege4ClientServer
Developer docs: http://protegewiki.stanford.edu/wiki/Protege_4_Development_Environment
Currently we are developing the HTTP version of the server in the http-metaproject-integration.
